A recent study reveals that millions of enrollees in the US Medicare Advantage program are compelled to switch plans due to unprecedented disruptions in the market. This marks the second consecutive year of dwindling growth for Medicare Advantage, with significant increases in plan exits threatening the stability of the program. As insurers like UnitedHealth and Aetna reduce their Medicare Advantage memberships, millions may lose their coverage, further complicating the landscape for seniors. Experts predict that 2026 could present even greater challenges for payers, highlighting a troubling trend of disenrollment and uncertainty in the future of Medicare Advantage.
